As a historical note, there was some reason to have the padding of 4
px, I think I recall in early Flash players, there was a bug in text
rending such that without that padding, the text was clipped off at
one end.

This was my reading of these functions, so "LzTextSprite#getTextHeight()"
returns the "Text height", whereas "LzTextSprite#getTextfieldHeight()"
returns the "Text Field height" [1]. That makes: "sprite.getTextHeight() +
2*2 == sprite.getTextfieldHeight()" (swf, single-line text, auto-sizing,
uniform text-format).
In dhtml, there is no distinction between a "Text height" and "Text Field
height". What we did to get the same results for dhtml compared to swf, was
to add a 4px padding, see "LzTextSprite.prototype.getTextSize(..)". At that
point, "swfsprite.getTextfieldHeight() == dhtmlsprite.getTextfieldHeight()"
should have yield the same result.
This also explains, why we went round in circles...
-LzInputTextSprite.prototype.getTextHeight = function () {
- var h = this.getTextfieldHeight();
- *if (this.quirks.emulate_flash_font_metrics) {*
- * h -= 4;*
- *}* - return h;
-}

I'm sure there is confusion, because we have this horrible quirk in DHTML
that adds 4 to all font measurements. But comparing the swf and DHTML
versions of getTextHeight, I see that the 4 is _not_ added there in DHTML,
so perhaps this is my mistake, getTextHeight is actually supposed to return
the height of the text.
I'll try reverting that bit of the change and see what happens...

If there is any confusion about flash text-metrics, you can take a look
at the ref for "TextLineMetrics" [1], which explains how flash treats
text-height (especially the 2px-gutter).
From "LzTextSprite.prototype.getTextHeight":
* This is the height of a single line of text in the current format
* *NOTE: this is not the clip textHeight, which "when autoSize is true
* is always 4 pixels less than _height" (which might explain the need
* for emulate_flash_font_metrics in DHTML?)*.

This is surely fallout from r9824 which was to fix the computation of
getTextHeight (c.f., LPP-4651). So, either I got that fix wrong, or, apps
were compensating for that measurement being wrong and now look wrong
because the measurement is right.
Feel free to ping me if you have questions, but perhaps you should
start by reviewing r9824 to see if you can spot an error. Max did review
it, Henry it is still awaiting your review, and Don, feel free to chime in!

I see this in the weather demo input text box. The text appears
scrunched in the upper left, and not even close to centered, in
Firefox/swf8/OSX.
I can't find any existing bug report filed on this, though
I'm sure I saw it mentioned in email in the last week or so.

Hello all,
I've been assigned LPP-6503, which seems to be a more general
problem
with <edittext>. To see this, open:
http://localhost:8080/trunk-doc5/docs/reference/lz.edittext.html
In the example, notice how the text in the edit box is very high.
Start
adding
more text and it moves up another pixel or two. I see this on >>
Safari
and Firefox on OSX. Maybe it has been reported already?
